使用UIActivityViewController在iPad上清空电子邮件正文

Question

我正在使用UIActivityViewController向我的应用添加分享。一切都在iPhone上按预期工作，但在iPad上，点击“UIActivityViewController”的电子邮件图标后，邮件视图控制器出现，但电子邮件的正文未设置（使用text1）和电子邮件viewController处于非活动状态，不允许用户输入收件人。

            let text1 = "this is the body of the email"
            self.finalizeDocument()
            let controller = UIActivityViewController(activityItems: [text1], applicationActivities: nil)
            controller.setValue("Siged document is attached", forKey: "subject")
            if let ppc = controller.popoverPresentationController {
                ppc.barButtonItem = self.shareButton!
            }
            self.presentViewController(controller, animated: true, completion: nil)

嘿，尝试这样的事情

1. 导入消息lib
2. 将邮件委托添加到班级

3. 撰写并发送您的信息

   import MessageUI
   
   class ViewController: UIViewController, MFMailComposeViewControllerDelegate{
   
       func someAwesomeFunction(){
            var subjectText = “ OMG  a subject”
            var bodtText = “ YOLO”
   
            var picker = MFMailComposeViewController()
            picker.mailComposeDelegate = self
            picker.setSubject(subjectText)
            picker.setMessageBody(bodtText, isHTML: true)
   
            presentViewController(picker, animated: true, completion: nil)
       }
